Component functions are also sometimes called Stateless Functional Components within the React community, or SFCs for short.

But I’m lazy, so I’ll just call them function components. You can too. It’s OK, I promise.

React components are just functions.

To be more specific, components are functions that tell React how to render one type of element. Each function takes a props object, and returns a new element that will be rendered in place of the original.
